Agree with Donkey Duke - go for the Jet!
A few Wideroe pilots have just left for Norwegian, despite the fact that they have been given the rating by the company, etc, etc... Wideroe is a very good company, but do you want to commute for 30 years? More than one pilot have realised that it wasn´t their cup of tea after a couple of years.
But if you live in the north of Norway or around Torp, it is a no brainer the other way around, go for Wideroe!
None have so far left Norwegian for Wideroe.
